That means that packages will be configured with -prefix=/usr/local. For this reason we recommend to use /usr/local for locally installed files. It is a good norm to keep the locally installed packages You can remove some files to remove dependencies on things like "libbzip2.dll" see and possibly avoid the libgcc.dll requirement by using "-static" at linking time. Unfortunately the gcc.exe it provides seems to create binary's that require files like "libgcc_s_dw2-1.dll" and "libwinpthread-1.dll" (etc.?) to accompany your executable, so can cause some difficulty there. If you use MSYS2 many packages can be easily installed by using pacman (for example pacman -S pkg-config).
Mingw for windows windows#
This installs "gcc.exe" commands that are actually built for MSYS2 but are the windows gcc compilers.
Mingw for windows install#
To compile FFmpeg, you need to install the mingw-w64 GCC environment (either in the i686 or x86_圆4 flavor). MSYS2 comes with a package management system called pacman adopted from Arch Linux, and allows to easily install binary packages from the commandline. Be careful not to run the MSYS2 Shell as this will result in FFmpeg's configure saying building an MSYS binary is not recommended and exiting.Īlternatively, you can also install GCC from MSYS2 system itself, and not need any of the MinGW-w64 instructions above: Then run the mingw32_shell.bat or mingw64_shell.bat command in the MSYS2 installation home. You will be able to then run configure (assuming you've installed a gcc to your PATH already). Msys provides shell utilities like make and bash. This can be done for example with:Ĭontrol Panel -> System -> Advanced -> Edit Environment Variables This will allow both the systemĪnd the msys shell to find programs provided by MinGW.

Note that by default the user home will be placed in MINGW_PATH/msys/1.0/home/USER, and that will be your working directory of the msys shell.įinally, you need to edit the system environment PATH variable, adding the MINGW_PATH/bin directory. Guide, when not explicitly specified, we'll use the UNIX mapped Check the output of the mount command, andįamiliarize yourself with the mapping mechanism. MinGW adopts a mounting mechanism to make Windows directories appear like native UNIX-like paths. Alternatively, or in case the MinGW entry is missing, you need to manually launch the MINGW_PATH/msys/1.0/msys.bat file. This is supposed to be a GNU/Unix environment, and you're supposed to know a bit of UNIX commands for getting through it. Click on it and it will launch a terminal with a bash shell. Once you install MinGW you should see in the Windows menu the "MinGW"Įntry with the option "MinGW shell". Note down this path (that we will call as "MinGW path" or Install in C:\MinGW but you can define the installation path whenĬonfiguring.
Mingw for windows download#
This will download most of the basic core packages. The recommended way to install MinGW/MSys is through the automated Go to and look for the "Download" page. The latter if you wanted to install something to your MINGW_PATH itself. To access DirectShow input devices you have to use MinGW-w64 as the compiler (or cross compiler), as straight MinGW headers don't have this functionality. Then configure your PATH appropriately, for instance mine looks like this:Ĭ:\installs\mingw-w64\i686-4.9.2-posix-dwarf-rt_v3-rev0\mingw32\bin c:\MinGW\msys\1.0\bin. To use MinGW-w64, install Msys using the MinGW setup, as above, but only check the "msys for developers option". This project does not have downloadable compilers by default you'll probably want the "mingw-builds" project, which provides pre-built compilers. The MinGW package provides gcc and headers. The first tends to be slightly more up to date than the latter, and offers more library compatibility, like DirectShow headers, so preferably use MinGW-w64. Some Windows-specific compilation information can be found in the official documentation.īoth offer working gccs for Windows. Note that the only strict requirement for compiling a plain vanilla version of FFmpeg (no external libraries) is MinGW (compilation environment) and Git required for downloading and updating the source code.Īlso note that sometimes it is easier to cross compile, see the Cross Compiling guide, which also may contain some hints/clues for compiling the various dependencies you'd need using MinGW, too.

You can still follow this guide if you want to manually compile FFmpeg. Tip: The Media Autobuild Suite can automatically build FFmpeg under Windows with several external dependencies.
